Yellowstone is America's first national park, and it spans Wyoming, Montana and Idaho. Elk, bison, wolves, grizzly bears and many other animals call this extraordinary place home.
There are loads of things to see and do in Yellowstone. During fair-weather months, fish, bicycle, picnic, boat, hike, or go on a horseback or wagon ride. If you visit during winter months, take your pick of exciting activities like downhill skiing or snowmobiling.
Viewing wildlife and the scenery can keep you quite busy, as there are numerous hot springs, more than 300 geysers (including Old Faithful) and excellent campgrounds to take in. Peak season is early July to late August, so make reservations well ahead of time or secure a campsite as early in the day as possible. During this time of year, the seven campgrounds in the park fill up quickly. No overnight camping is permitted outside of these grounds unless you secure a backcountry camping permit.
